Jon Hamilton is a correspondent for NPR's Science Desk. Currently he focuses on neuroscience, health risks, and extreme weather.

Following the 2011 earthquake and tsunami in Japan, Hamilton was part of NPR's team of science reporters and editors who went to Japan to cover the crisis at the Fukushima Dai-ichi nuclear power plant.

Hamilton contributed several pieces to the Science Desk series "The Human Edge," which looked at what makes people the most versatile and powerful species on Earth. His reporting explained how humans use stories, how the highly evolved human brain is made from primitive parts, and what autism reveals about humans social brains.

In 2009, Hamilton received the Michael E. DeBakey Journalism Award for his piece on the neuroscience behind treating autism.

Before joining NPR in 1998, Hamilton was a media fellow with the Henry J. Kaiser Family Foundation studying health policy issues. He reported on states that have improved their Medicaid programs for the poor by enrolling beneficiaries in private HMOs.

From 1995-1997, Hamilton wrote on health and medical topics as a freelance writer, after having been a medical reporter for both The Commercial Appeal and Physician's Weekly.

Hamilton graduated with honors from Oberlin College in Ohio with a Bachelor of Arts degree in English. As a student, he was the editor of the Oberlin Review student newspaper. He earned his master's degree in journalism from Columbia University, where he graduated with honors During his time at Columbia, Hamilton was awarded the Baker Prize for magazine writing and earned a Sherwood traveling fellowship.

When the American Psychiatric Association releases its new Diagnostic and Statistical Manual of Mental Disorders-- DSM-5 -- this weekend, lots of journalists and commentators will refer to it as "psychiatry's bible."

That's a term that makes the manual's authors and other mental experts cringe.

The American Psychiatric Association is about to release an updated version of its Diagnostic and Statistical Manual of Mental Disorders. The DSM helps mental health professionals decide who has problems such as depression, anxiety and schizophrenia.

Psychiatry's new manual, DSM-5, has been nearly 20 years in the making. During that time, scientists have learned a lot about the brain. Yet despite some tweaks to categories such as autism and mood disorders, DSM-5 is remarkably similar to the version issued in 1994.

A study of genetically identical mice is providing some hints about humans. How can one identical twin be a wallflower while the other is the life of the party?

The study of 40 young mice found that their behavior grew increasingly different over three months, even though the mice shared the same genes and lived in the same five-level cage, researchers report Thursday in the journal Science.

This is a story about a duck. More precisely, it's a story about what your brain just did when you read the word "duck."

Chances are, your brain created an image of a web-footed waterfowl. It also may have recalled the sound of quacking or the feel of feathers. And new research suggests that these mental simulations are essential to understanding language.

When Superstorm Sandy inundated lower Manhattan last year, thousands of lab animals drowned and many scientists lost months or even years of work. One of those scientists is Gordon Fishell, a brain researcher at New York University.

Just hours before Sandy reached New York, Fishell says, he began to worry that animals housed in a basement below his lab were in danger. "I realized Hurricane Sandy and high tide were going to coincide at Battery Park, which is right where my lab is," he says.

President Obama has announced an ambitious plan to explore the mysteries of the human brain.

In a speech Tuesday, Obama said he will ask Congress for $100 million in 2014 to "better understand how we think and how we learn and how we remember." Other goals include finding new treatments for Alzheimer's disease, epilepsy and traumatic brain injury.

A large new government study should reassure parents who are afraid that kids are getting autism because they receive too many vaccines too early in life.

The study, by researchers at the Center for Disease Control and Prevention, found no connection between the number of vaccines a child received and his or her risk of autism spectrum disorder. It also found that even though kids are getting more vaccines these days, those vaccines contain many fewer of the substances that provoke an immune response.

Loneliness hurts, but social isolation can kill you. That's the conclusion of a study of more than 6,500 people in the U.K.

The study, by a team at University College London, comes after decades of research showing that both loneliness and infrequent contact with friends and family can, independently, shorten a person's life. The scientists expected to find that the combination of these two risk factors would be especially dangerous.

As far back as he can remember, George McCann lived in fear. When he was asleep he would have horrific nightmares filled with violent images. When he was awake, he often felt threatened by people, including members of his own family. And when he felt threatened, he would become aggressive, even violent.

George spent his childhood certain that something very bad was going to happen. And when he was 12, it did. His unrelenting fears led to a violent outburst at school. And George landed in a psychiatric hospital.

The disease is now the sixth leading cause of death in the U.S., and figures released Tuesday by the Alzheimer's Association show that deaths from the disease increased by 68 percent between 2000 and 2010.

Scientists are beginning to understand how people tune in to a single voice in a crowded, noisy room.

This ability, known as the "cocktail party effect," appears to rely on areas of the brain that have completely filtered out unwanted sounds, researchers report in the journal Neuron. So when a person decides to focus on a particular speaker, other speakers "have no representation in those [brain] areas," says Elana Zion Golumbic of Columbia University.

If food is love, Americans must love their kids a lot. About one-third of children and adolescents in the U.S. are overweight or obese.

And our emotional response to food may be one of the reasons so many kids eat so much, according to a poll by NPR, the Robert Wood Johnson Foundation and the Harvard School of Public Health. The poll found that in more than a quarter of families, food is considered an important way to show affection.

A common vitamin supplement appears to dramatically reduce a woman's risk of having a child with autism.

A study of more than 85,000 women in Norway found that those who started taking folic acid before getting pregnant were about 40 percent less likely to have a child who developed the disorder, researchers reported in the Journal of the American Medical Association.

It's been a mixed year for Alzheimer's research. Some promising drugs failed to stop or even slow the disease. But researchers also found reasons to think that treatments can work if they just start sooner.

Scientists who study Alzheimer's say they aren't discouraged by the drug failures. "I actually think it was a phenomenal year for research," says Bill Rebeck, a brain scientist at Georgetown University.

An old complaint about the safety of childhood vaccines is finding new life at the United Nations.

The U.N. Environment Program is considering a ban on thimerosal, a vaccine preservative that is widely used in developing countries. The program expects to make a decision sometime after a final meeting on the issue in January.

A massive research project in California is beginning to show how genes, health habits and the environment can interact to cause diseases. And it's all possible because 100,000 people agreed to contribute some saliva in the name of science.
